(195 cards)
1
Q
Ectopic pregnancy
A
RF = Previous ectopic / PID / Surgery to fallopian tubes / Coils / Old age / Smoking
Presentation - typically 6-8 weeks gestation with missed period - constant lower abdo pain (RIF / LIF), Vaginal bleeding, abdominal tenderness +/- pain radiation to the L shoulder
O/E bimanual palpation reveals cervical motion tenderness
!TIP - always ask about anemia symptoms e.g dizziness, syncope etc
Investigation
* * Pregnancy test - Women may have a +ve pregnancy test. Normally HCG doubles every 48hrs so a rise <63% after 48 hours indicates an ectopic (a fall of >50% indicates miscarriage)
* Gold standard =** transvaginal ultrasound**
USS will show a ‘blob/bagel’ sign which does not move with the ovaries- gestational sac containing a yolksac or fetal pole in the fallopian tube
2
Q
Management of Ectopic pregnancy
A
- Expectant management - if <35mm unruptured ectopic with no visible heartbeat, no significant pain and HCG <1500
- Medical management (Methotrexate IM) - if HCG < 5000 & same as above
- Surgical management (Salpingectomy 1st line, Salpingotomy if risk of infertility)- if pain, adnexal mass >35mm, Visible heartbeat or HCG >5000
!NOTE - rhesus -ve women having surgical removal need Anti-D prophylaxis
3
Q
Miscarriage
A
Sx = Painless vaginal bleeding
Types;
* Threatened = vaginal bleeding with closed cervix but alive fetus
* Inevitable = Vaginal bleeding + open cervical os
* Incomplete = Retained products of conception after miscarriage
* Complete = gestational sac present but no embryo
Investigations;
1. 1st line = **Ultrasound **
4
Q
Features to look for on USS in early pregnancy + indicators of miscarriage
A
- Mean gestational sac diameter - *should be >25mm - this is when you would expect to see a fetal pole
- Fetal pole + crown rump length - this should be 7mm - this is when you would expect to see a heartbeat
- Fetal heartbeat - Pregnancy is viable when heartbeat is visible
Note - if no fetal pole is seen but sac >25mm then repeat scan in 1 week before confirming miscarriage. Also if crown-rump length >7mm but no heartbeat or crown-rump length <7mm with a heartbeat repeat in 1 week before confirmation.
5
Q
Management of miscarriage
A
<6 weeks gestation = expectant management + repeat urine pregnancy test in 7-10 days.

Where the placenta is attached to lower portion of uterus (may cover cervical os)
Features;
* Many are asymptomatic
* Painless vaginal bleeding - typically 36+ weeks
Grading;
1 - placenta is lower than uterus but not reaching internal os
2 - Placenta reaches but does not cover internal os
3 - placenta is partially obstructing internal os
4 - Placenta is completely covering internal os
Invx = usually picked up on 20 week anomaly scan

* Vaginal bleeding
* Shock (hypotension + tachycardia) - *pt may have no clear sign if concealed abruption.
* CTG abnormalities
O/E the pt may have a "woody" appearance to the abdomen (suggesting haemorrhage)
Invx; largely a clinical diagnosis - *Can do USS to rule out praevia as a cause of bleed*
Management;
* If < 36 weeks + fetal distress = C section (if not fetal distress just monitor)
* If > 36wks = vaginal delivery or C section if fetal distress
*NOTE - ensure to give maternal corticosteroids if delivering < 34 weeks + give Anti-D prophylaxis if woman is rhesus -ve.

Diagnosis = picked up on USS or at birth when placental delivery is difficult. MRI can be used to asses depth and width of invasion.
Mx;
* Planned C secrion between 35 - 36 + 6 weeks (give corticosteroids)
* If extensive disease then hysterectomy may be recommended during surgery or can try and do uterus preserving surgery.
If natural birth (i.e was not pre diagnosed) but delayed placental delivery pt may need hysterectomy.
56
Management of baby born to Hep B surface antigen +ve mothers
Hep B vaccine and 0.5ml HBIG within 12 hours. ofbirth

* 1st trimester if 4+ risk factors
* 28 weeks + if 3+ risk factors
If contraindications for LMWH (e.g bleeding disorder or postpartum haemorrhage) Give intermittent pneumatic compression stockings.
60
Management of PE/VTE in pregnancy
Thrombolysis is obvious contraindicated in pregnancy (can cause catostrophic haemorrhage of placenta)
So for massive PE + haemodynamic comprimise:
1. Unfractionated heparin
2. Surgical embelectomy.
61
Hb Targets during/after pregnancy
Booking scan >110g/L

RF = placenta praevia /IVF / Multiple pregnancy
Presentation; Classic triad;
1. Rupture of membranes followed by
2. Vaginal bleeding and
3. Fetal distress
Diagnosis = Sometimes picked up antenatally with USS. Often presents during labour with vaginal bleeding or during vaginal examination.
Mx = Carries v high fetal morality due to risk of asphyxiation or hypoxia.
If pre-diagnosed then Elective C section at 34-36weeks (+ corticosteroids).
If presenting in labour = push baby back in (NOT cords) and go to emergency C section
63
Management of stillbirth
Vaginal birth is 1st line (unless contraindicated)
* Give mifepristol +/- Misoprostol to induce labour
Expectant management can be done
*Give Carbergoline (dopamine agonsit) after birth to suppress lactation.
64
Chorioamnionitis
Bacteria infection of the placenta and amniotic fluid
Sx;
* Uterine tenderness
* Bad smelling amniotic fluid (brown discharge)
* Baseline fetal tachycardia
Mx = prompty delivery of fetus (by C section if needed) followed by IV antibiotics
65
Management of antenatal GBS
Intrapartum IV Benzylpenecillin - required to reduced neonatal transmission.
Note - Universal GBS screening is not offered. However women who have had GSB in previous pregnancies should be offered intrapartum prophylaxis or testing at 35-37 weeks as their risk remains 50%.
IAP should be offered to any women in preterm labour (regardless of GBS status) and those with fever >38 degrees during labour
66
Aortocaval compression
This can occur if a pregnant lady lays on her back and causes compression of the IVC and aorta, reducing venous return to the heart therefore reducing CO leading to hypotension.
Place woman in the left lateral position to relieve the compression and improve venous return to the heart
67
When should you first begin to feel fetal movements
between 18-20 weeks (sometimes 16 if multiparous)
If no movements have been felt by 24 weeks then further investigation is needed.
68
RCOG definition of reduced fetal movements
<10 movements in 2 hours for pregnancies >28 weeks
69
RF for reduced fetal movements
* Posture - *generally less prominent when sitting/standing*
* Distraction
* Placental position - *anterior placentas may cause less feeling*
* Fetal position - *anterior fetal position means movements are less noticable*
* Body habitus

VE every 4 hours to check progression
Maternal urine dip (ketons/protein) every 4 hours
73
What is the normal fetal lie
Longitudinal cephalic
74
Transverse lie
This is common <32 weeks but usually does correct itself.
Management = if >36 weeks then ECV should be tried (can't be done if ROM already). If unsuccesful then C section.

P-PROM
Preterm pre-labour rupture of membranes
Invx = Speculum reveals pooling of amniotic fluid in the vagina
Mx x = Prophylactic Erythromycin (to prevent chorioamnionitis) + Induction of labour (if 34+ weeks)
make sure to give maternal corticosteroids.
79
What tests can be done to confirm rupture of membranes
1. IGFBP-1 = a protein present in amniotic fluid (raised levels in vaginal fluid indicates PPROM)
2. PAMG-1
80
Pre-term labour with intact membranes
Regular painful contractions + cervical dilation but no rupture.
Dx = if <30 weeks clinical diagnosis.
If >30 weeks;
* Transvaginal USS to assess cervical length (if >15mm then preterm labour is unlikely)
* Fetal fibronectin - found in the vaginal during labour (<50ng/ml means labour is unlikely)
Mx;
* If between 24 and 33+6 then use tocolysis with Nifedipine
* Maternal corticosteroids
* IV mangesium sulfate (if delivering <34 weeks to protect babys brain)
* Delayed cord clamping (can increase circulating blood volume and Hb in baby at birth)
81
Bishop score
Scoring system to determine the ripeness of the cervix.
Based on;
* Fetal station
* Cervical position
* cervical dilation
* cervical effacement
* cervical consistency
Score 8+ shows a ripe cervix and high chance of spontaneous labour
82
Options for inducing labour
1. Membrane sweep - *used from 40wks +, may induce labour within 48hrs*
2. Vaginal Dinoprostone - *prostaglandin E2 - done in hospital setting*
3. Cervical ripening balloon - *used when prostaglandins are not preferred e.g previous C section or multiparous women or if prostaglandins didn't work*
4. Oxytocin infusion - *often used after dinoprostone*
5. Oral mifepristone + misoprostol (used when fetal death has occured)
83
What should the baseline rate be on CTG
110-160bpm
100-109 or 160-180 is non-reassuring
<100 or >180 = Abnormal/concerning
84
What should variability be on CTG
Normal variance = between 5-25
Non-reassuring = <5 for 30-50mins or >25 for 15-20 mins
Abnormal/concerning = <5 for 50+ minutes, >25 for 25+ minutes.
85
Types of decelerations on CTG and what they mean
1. **Early decelerations** = gradual dips + recoveries in HR corresponding with uterine contractions. Fairly normal
2.** Late decelerations** = gradual falls in HR starting after uterine contractions - **concerning as can indicate hypoxia **
3.Variable deceleratons - Abrupt decelerations unrelated to uterine contractions. A fall of >15bpm from baseline may indicate** cord compression** (*if bried period of acceleration before + after then fairly reassuring)*
4.**Prolonged decelerations** - last between 2-10mins with a drop of >15bpm = cord compression + an emergency
86
What CTG pattern may be seen in vasa praevia
A rare pattern of CTG indicating severe fetal anemia (often due to vasa previa)
- shows a sine wave, with regular ups and downs and an amplitude of 5-15
87

2. then give IM oxytocin
3. Palpate the abdomen to assess for uterine contraction
4. Use controlled cord traction to help deliver the placenta
90
Cord prolapse management
Main RF = fetus in abnormal lie or AROM.
Management;
* Emergency C section
* Cord should be kept warm & wet with minimal handling (to prevent vasospasm)
* Women should be positioned on all fours
* Limit compression on the cord - push baby back inside if out
* Give tocolysis (e.g terbutaline)- to minimise contractions whilst waiting for surgery
91

Zavanelli's manouevre
Push the babys head back into the vagina so baby can be delivered by C section
95
Indications for instrumental delivery
Failure to progress
Fetal distress
Maternal exhaustion
Control of the head in various fetal positions
Note - to quality for this the cervix must be fully dilated an dthe head of the baby should be low (> +1 fetal station) + One off dose of co-amoxiclav needed.

Ventouse
97
Main complication of Forceps delivery
Facial nerve palsy
Bruising to babies face
98

Presentation;
* large postpartum haemorrhage
* Maternal shock
* Collapse
Mx = life threatening emergency!
1. Johnson's manouevre = use hand to push fundus back up and hold for several minutes - then give oxytocin to create tension and leave it there

How does endometriosis present
Cyclical pelvic pain + Deep dyspareunia. May have dysmenorrhoea / infertility / urinary or bowel symptoms.
*Consider extra-pelvic manifestations e.g Haemoptysis and bowel/urinary symptoms.
Adhesions may cause chronic, non-cyclical pain.
125
Investigations for endometriosis
Pelvic exam should be performed which may show pelvic massess or tissue in the posterior fornix etc.
1. Transvaginal USS - this may show large endometriomas & **Chocolate cysts **
2. **Gold standard & needed for diagnosis** = Laparoscopy + biopsy
3. If suspecting **adenomyosis then MRI** is best invx
126
Management of endometriosis
1st line = NSAIDs + analgesia
2. Hormonal treatment = Mirena coil, COCP or POP

Presentation; Typically presents in younger women (more common on those with COCP or pregnant)
* Postcoital bleeding
* Increased vaginal discharge
* Dyspareunia
O/E - speculum will reveal a well demarcated border between the redder columnar epithelium and pale pink squamous epithelium.
Management;
* Asymptomatic ones require no treatment - *Typicalyl resolves with age COCP cessation or end of pregnancy *
* Problematic bleeding is a indication for treeatment - either silver nitrate cuterization or cold coagulation
145
Nobathain cysts
Fluid filed csysts on the surface of the cervix. Usually up to 1cm in size.
Cause - *often happens after birth, trauma or cervicitis - due to mucus from the columnar epithelium becoming trapped by the squamous epithelium.
Usually asymptomatic - O/E smooth rounded bumps on the cervix usually near the os. Typically 2mm-30mm in size with whiteish yellow colour

Presentation;
* Unilateral cyst - tender on palpation and 1-4cm in size lateral to the introitus
* An abscess will be hot, tender and red and >4cm in size
Management;
- Bartholian cyst will resolve with good hygeine + warm compresses (biopsy may be needed if age >40yrs and suspecting vulval malignancy)
- Bartholian abscess needs Abx and may need a word catheter for pus drainage or marsupilization (surgcial drainage)

Complications = 5% risk o developing vulval squaous cell carcinoma.
152
Androgen insensitivity syndrome
Condition where cells are unable to respond to androgen hormones due to a lack of androgen receptors.
X-linked recessive condition
Patients are geneticaly male (XY) - but the absent response to tesosterone ledas to increased oestrogen production resulting in female secondary characteristics.
Presentation;
- Externale female genitalia + breast tissue but will have testicles in their abdomen/inguinal canal (no ovaries, uterus etc): *This is because the testes produce Anti-mullerian hormone which prevents the production of uterus etc *
Invx = Raised LH + FSH, Normal/raised tesosterone for a post-pubesent male + Raised oestrogen (for a male)
Management = refer to specialists.
Bilateral orchidectomy needed to prevent formationof testicular cancer
Oestrogen therapy.

Oestrogen only HRT does not inc risk of CAD.
165
MOA & SE's of Clonidine
Alpha-2 adrenergic receptor agonist
It lowers BP and HR & is helpful for vasomotor symptoms + hot flushes
SE = dry mouth, headaches, dizziness, fatigue. Sudden withdrawl may result in rapid BP increase.
166
Steps to choosing the most suitable HRT
1. Do they have local or systemic symptoms? - *local can be treated with topical oestrogen*
2. Do they have a uterus? *no uterus = oestrogen only. Uterus = combined for endometrial protection (mirena coil licensed for 4yrs)*
3. Have they had a period in the past 12 months? perimenopausal = cyclical combined HRT with breakthrough bleed, postmenopausal = continuous.
167

MOA = Prevents ovulation, thickens cervical mucus + inhibits the proliferation of the endometrium.
Options;
1. 1st line contraceptive = microgynon or leostrin (as levonorgestrol has lower VTE risk)
2. 1st line for premenstrual syndrome = Yasmin continuous use (drospirenone has anti-androgen & anti-mineralocorticoid activity so helps with bloating + mood changes)
3. 1st line for Acne / Hirtuism = Dianette (cyproterone acetate hs anti-androgen effects - but higher VTE risk so stop after 3 months)
171

2. Desorgestrel (e.g cerazette) = can be taken 12hrs later
MOA = inhibits ovulation, thickens cervical mucus, inhibits proliferation of endometrium + reduces ciliary action in fallopian tubes
SE's: 40% have regular bleeding and 40% have troublesome bleeding. Breast tenderness, headaches, acne.
Increases risk of ovarian cysts, ectopic pregnancy _ breast cancer.
174
Advice for additional contraception when starting the POP
Day 1-5 = immediate protection
Day 5+ = additional contraception for 48hrs.
If starting a POP when currently on COCP - best to change on day 1-7 of hormone free period as no additional contraception needed. If switching when taking the active pills then additional contraception needed for 48hrs.
175
Progesterone Depot
99% effective but 94% with typical use.

176
Progesterone implant
99% effective.
Pros = no restrictions for use in obese pts or those with VTE risk. no effect on bone mineral density and can make periods stop altogether.
Cons =requires minor op. Can worsen acne. Porblematic bleeding. Can become deeply implanted.
**Affected by enzyme inducers **(e.g rifampicin)
